The Japanese word ikigai, which has recently gained attention worldwide and enjoys widespread use, refers to a passion that gives value and joy to life. The author who prompted its craze speaks about the word’s appeal and the effects it has on mental and physical health.

The Japanese tradition of Shinrin-yoku or 'forest bathing' can be traced back several centuries, but the term was popularlised in the 1980's. It refers to slowing down and spending mindful time in nature. Gentle and meditative, the practice is seen as an antidote to the stresses of modern living.

Whether you call it a fitness trend or a mindfulness practice (or a bit of both), what exactly is forest bathing? The term emerged in Japan in the 1980s as a physiological and psychological exercise called shinrin-yoku (“forest bathing” or “taking in the forest atmosphere”). The purpose was twofold: to offer an eco-antidote to tech-boom burnout and to inspire residents to reconnect with and protect the country’s forests.

The Japanese quickly embraced this form of ecotherapy. In the 1990s, researchers began studying the physiological benefits of forest bathing, providing the science to support what we innately know: time spent immersed in nature is good for us. While Japan is credited with the term shinrin-yoku, the concept at the heart of the practice is not new. Many cultures have long recognized the importance of the natural world to human health.

Forest bathing is not just for the wilderness-lover; the practice can be as simple as walking in any natural environment and consciously connecting with what’s around you. For a more structured experience, you can join trained guides for a meditative two- to three-hour ecotherapy excursion. Here are five places to try forest bathing.

Tens of millions of Japanese perform a specific exercise routine at least once a week. Could rajio taiso help people live longer lives?

Depression was not widely recognised in Japan until the late 1990s - then a campaign called it a "cold of the soul" and sales of anti-depressants boomed.
